Washing machine

Abstract

A washing machine includes an external cabinet, an outer tub installed inside the external cabinet, a spin basket rotatably installed inside the outer tub and a plurality of suspension units for suspending the outer tub with respect to the external cabinet. Each of the suspension units comprises: a suspension bar for connecting the outer tub to the external cabinet; a main damper combined with one end of the suspension bar; and an auxiliary damper combined with the one end of the suspension bar, adjacent to said main damper. Accordingly, vibrations and noises of the outer tub can be reduced effectively.

What is claimed is: 
     
       1. A washing machine including an external cabinet, an outer tub installed inside said external cabinet, a spin basket rotatably installed inside said outer tub and a plurality of suspension units for suspending said outer tub with respect to said external cabinet, each of said suspension units comprising: a suspension bar for connecting said outer tub to said external cabinet;   a main damper combined with the one end of said suspension bar; and   an auxiliary damper combined with the one end of said suspension bar, adjacent to said main damper;   wherein each of said main and auxiliary dampers has a hollow cylinder and a piston frictionally slidable inside said cylinder, and said suspension bar axially passes through said cylinder and is combined with said piston.   
     
     
       2. A washing machine including an external cabinet, an outer tub installed inside said external cabinet, a spin basket rotatably installed inside said outer tub and a plurality of suspension units for suspending said outer tub with respect to said external cabinet, each of said suspension units comprising: a suspension bar for connecting said outer tub to said external cabinet;   a main damper combined with the one end of said suspension bar; and   an auxiliary damper combined with the one end of said suspension bar, adjacent to said main damper;   wherein said main and auxiliary dampers are jointly connected by said single suspension bar; and   said single suspension bar is provided at the one end thereof with a joint having a plurality of forks, and said main and auxiliary dampers are combined with said plurality of forks of said joint, respectively.
